    Rat liver nuclei contain a protein phosphatase that is indistinguishable from the catalytic subunit of protein phosphatase-1 in its molecular mass, sensitivity to inhibitor-1 and inhibitor-2 and specificity for the β-subunit of phosphorylase kinase. This activity is not bound to the outer nuclear membrane, but located within the nucleus. The average level of protein phosphatase-1 activity in nuclei is at least 5-fold higher than its average extranuclear concentration.
